Question

A washing Machine is marked as 220V - 1500W. What do you understand from this.​

Answer 1

Answer:

this means that the washing machine will work with max output power of 1500 W if you provide a voltage of 220V

Answer 2

good question for the people who don't know about power delivery and consumption :

There is a small technical difference in between these two that is:

. . The power generated by an electrical source is always calculated in VA or KVA Or MVA because there is no power factor, in othe r words there is no power dissipation so what amount of power is generated, the same is calculated as power .

Now, we come to the point ; difference between the 1500 watt and 1000 watt electrical home appliances is that both the appliances indicates their power consumption as per the formulae W = V I Cos 0 (theeta) which is equal to 1500 Watt for the second one and 1000 Watt for the 1st home appliance of 1000W.

. . . The electrical consumption unit is calculated as

1 unit = 1000 W x 1 hour means if a 1000 W home appliance is used continuesly for one hour (1 Hr ) it will consume 1 unit or 1 kilowatt-hour electric power. Similarly an appliance marked 1500 W it will consume one and half unit.
